Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional vehicle-mounted battery cooling structures face reduced cooling efficiency and increased noise due to the complex arrangement of ducts with numerous sharp bends, which result in high flow resistance in limited spaces.
Innovation Solution
A vehicle-mounted battery cooling structure that positions the battery and cooling fan in separate mounting areas, such as between the front seats and under the rear seat, allowing for a straighter path for cooling air to flow, minimizing duct complexity and flow resistance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Volume of moving object
If the battery and cooling fan are arranged in a limited space at the front seat, then the cooling structure can be compact, but the duct becomes complicated with sharp bends causing high flow resistance and reduced cooling efficiency
Solution Approach 1:
The patent extends the cooling system into the longitudinal dimension of the vehicle by placing the cooling fan in the rear seat area while keeping the battery in the front seat area. This dimensional expansion allows the duct to connect components with a straighter path, reducing bends and flow resistance while maintaining system compactness.
2Length of stationary object
If the duct is bent many times in a limited space, then the battery and fan can be positioned close together, but the flow resistance increases and cooling efficiency decreases
Solution Approach 1:
By utilizing the longitudinal space from front to rear seats, the patent creates a straighter duct path that reduces the number of bends. The duct connects the battery in the front to the fan in the rear with minimal angular changes, lowering flow resistance despite the increased longitudinal span.
3Area of stationary object
If the duct has sharp bends to fit in limited space, then the installation space is reduced, but the noise increases and cooling performance deteriorates
Solution Approach 1:
The patent redistributes components along the longitudinal axis of the vehicle, placing the battery in the front seat area and the cooling fan in the rear seat area. This spatial reconfiguration allows for a straighter duct connection that reduces turbulent flow, thereby lowering noise and improving cooling performance while utilizing the vehicle's longitudinal space efficiently.
